“…Graphene has attracted interest as a novel lubricating material with excellent tribological properties, thermal conductivity, and mechanical strength [14][15][16]. Jyoti et al [17], reported the influence of nano-graphite and carbon nanoparticles in SAE-30 and found a reduction of 13 times in friction, seven times in wear, and 15% in total fuel consumption using nano-graphite particles. Fe et al [18], investigated the tribological performance of different oxide nanoparticles in 10W-30 and observed that the friction and wear were reduced by 80% and 50%, respectively, using Al 2 O 3 .…”

The use of nano-additives improves the performance of lubricants by minimizing energy loss due to friction and wear. In this study, the tribological properties of cylinder liner-piston ring were improved by modifying monolayer graphene with surfactants. Additionally, surface chemical chromium plating and chemical heat treatment were conducted on the friction surfaces of specially made piston ring samples to further enhance the piston ring friction. The use of nano-additives, specifically 0.05 wt% modified graphene nano-lubricant, exhibited the best lubrication performance. Compared to the base oil, it reduced the friction coefficient by approximately 31.1% and improved the anti-wear performance by approximately 59.6%. In addition, the effect of the graphene nano-lubricant on the friction performance of chromium- plated samples was more substantial than that of the chemically heat-treated samples. Under high-temperature and heavy-load conditions, the friction coefficient was reduced by 15.5% and 34%, respectively, when compared to the base oils. This can be attributed to the porous surface of the chromium-plated sample, which promotes the storage of the graphene nano-lubricant. The findings of this study highlight the synergistic effect of graphene additives and piston ring surface treatment on the tribological performance.

Recent Advances in Preparation and Testing Methods of Engine-Based Nanolubricants: A State-of-the-Art Review

Reducing power losses in engines is considered a key parameter of their efficiency improvement. Nanotechnology, as an interface technology, is considered one of the most promising strategies for this purpose. As a consumable liquid, researchers have studied nanolubricants through the last decade as potential engine oil. Nanolubricants were shown to cause a considerable reduction in the engine frictional and thermal losses, and fuel consumption as well. Despite that, numerous drawbacks regarding the quality of the processed nanolubricants were discerned. This includes the dispersion stability of these fluids and the lack of actual engine experiments. It has been shown that the selection criteria of nanoparticles to be used as lubricant additives for internal combustion engines is considered a complex process. Many factors have to be considered to investigate and follow up with their characteristics. The selection methodology includes tribological and rheological behaviours, thermal stability, dispersion stability, as well as engine performance. Through the last decade, studies on nanolubricants related to internal combustion engines focused only on one to three of these factors, with little concern towards the other factors that would have a considerable effect on their final behaviour. In this review study, recent works concerning nanolubricants are discussed and summarized. A complete image of the designing parameters for this approach is presented, to afford an effective product as engine lubricant.

In previous years, nanolubricants have gained attention in terms of their use as heat transfer fluids in applications such as engine cooling and air conditioning. Carbon-based nanolubricants have attracted great interest due to their superior heat transfer performance. To date, the stability of a carbon-based nanolubricant is crucial if the enhanced properties are to be retained after the fabrication process. In this context, the current research aims to review the stability and thermophysical properties of carbon-based nanolubricants. Recent works on these nanolubricants are summarized herein, including the method of preparation and improvements in their properties. The factors that affect the thermal conductivity and viscosity are also discussed, and finally, the applications of nanolubricants are described. The recent studies of nanolubricants are summarized and opportunities for further improvements in their efficiency are suggested.
